It's really not that difficult. Do you want her to initiate the conversation? If so, then pretend she said 'hi' before you run into her cart.
I'll have to check out Central Market tomorrow. My plans got cancelled, so I'm open to go hang out. I might spend some time in the wine or produce sections. Maybe I'll do something embarassing like pull the bottom grapefruit, and topple the pyramid. So all those hot women will have sympathy for me and help me out.
